The danger signals are red while the eye is more sensitive to yellow because-
  • a)
    absorption in red is less than yellow and hence red is visible from a distance
  • b)
    scattering in yellow light is less than red
  • c)
    the wavelength of red light is more than yellow light
  • d)
    none of the above reasons
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
The danger signals are red while the eye is more sensitive to yellow ...
The primary reason why the color red is used for danger signals is that red light is scattered the least by air molecules. The effect of scattering is inversely related to the fourth power of the wavelength of a color. The wavelength of red light is more than yellow light.
Hence, the correct option is (C)
